    Abstract: This invention discloses a novel method for fabricating solar cells. Using the existing screen-printing, masking or photolithography techniques, a P-type or N-type diffusion source is coated on the sites of an N-type or P-type silicon wafer desired for forming electrodes. Then, a low dose P-type or N-type diffusion source is in situ diffused into the N-type or P-type silicon wafer together with the P-type or N-type diffusion source coated on the N-type or P-type silicon wafer in the furnace. Thereafter, a P−/P+ or N−/N+ diffusion region is formed within the N-type or P-type silicon wafer. Finally, electrodes aligned to the P+ or N+ diffusion region are formed by means of screen-printing. Then, a solar cell with high photocurrent and low series resistance can be obtained.
